Patent JP-H0222679-A (JP)
Title: Illuminator
Inventor: MATSUDA SHINYA
IPC: G03G15/04
Filed: 1988-07-08
Abstract: PURPOSE:To improve copying performance by means of a small-sized illuminator and at a low cost by providing a first auxiliary reflecting plane, which alters the advancing direction of a first illumination optical path, on the mid-way of the first illumination optical path, and also providing a second auxiliary reflecting plane, which alters the advancing direction of a second illumination optical path, on the mid-way of the second illumination optical path. CONSTITUTION:The illuminator has the first illumination optical path P, second illumination optical path Q, and reflecting optical path R; in the first illumination optical path P, light from a light source tube lamp 3 is reflected from the front surface 4a of a main reflecting mirror 4 and the first auxiliary reflecting mirror 5a so that it is condensed in a form of a slit on an original plane 11; in the second illumination optical path Q, light from the light source tube lamp 3 is reflected from the rear surface 4b of the main reflecting mirror 4 and the second subreflecting mirror 5b so that it is condensed in a form of a slit on the original plane 11; in the reflecting optical path R, light is reflected from the original plane 11 so that it slit-exposes the surface of a photosensitive body drum 9. The both auxiliary reflecting mirrors 5a and 5b are formed in such a way that their respective incident angles, beta1 and beta2, of the reflected light from the original plane plane is minimized as much as possible; therefore, a black strip on an image is almost eliminated even when an original 20 having an uneven surface is copied. This accomplishes miniaturization and reduces cost, and improves the performance of the device.

Title: Magnetic head supporting device
Inventor: OKITA MASAO
IPC: G11B17/32
Filed: 1989-07-05
Abstract: PURPOSE:To realize magnetic recording with high density and to prevent the deformation of a magnetic disk from occurring by providing a positive pressure generating part which generates positive pressure from the upstream side to the downstream side in the rotating direction of the disk, a stable floating part for the disk, and a negative pressure generating part. CONSTITUTION:An air current is generated along the surface of the disk 12 when the disk 12 is rotated at high speed confronting with a supporting plate 5, and flows in a flat plane 11 formed obliquely at the front edge of the supporting plate 5, then, the posistive pressure is generated at the flat plane part 11. When the air flows from the flat plane part 11 to a limb part 8, a gap at the part 8a of the upstream side in the rotating direction of the limb part 8 is increased larger than that at the downstream side, which generates stable positive pressure. The parts 8b at both sides along the rotational direction of the limb part 8 hold a non-contact state with the disk 12 while keeping the gap smaller than that of the part 8a. The air passing through the part 8a generates negative pressure in the case of arriving at a recessed part 10, and the disk 12 is attracted, and the tensile force is generated, and a gap forming part 4 is stuck hermetically on the recording plane of the disk 12, which enables the recording with high density to be performed.

Title: Method of evaluating abrasion of piston
Inventor: SUDA HIDEO
IPC: G06T1/00
Filed: 1994-06-30
Abstract: PURPOSE:To detect an abrasion of a processed groove and to determine the degree of the abrasion by calculating a degree of contact with the processed groove from a difference between a maximum value and a minimum value of waveform data obtained by conversion of a developed image of the outer peripheral surface of a piston. CONSTITUTION:A developed image of the outer peripheral surface of a piston 1 to be evaluated which is set on a rotary stage 2 is picked up by a lens system 6 and a CCD sensor 5 while the piston 1 is rotated, so as to obtain original image data from which the position of a processed groove having previously been formed in the piston is calculated. Next, the original image data are converted into waveform data which indicate a density for every position on the piston 1 along an axis orthogonal to the processed groove. Further, a degree of contact with the processed groove (a condition of abrasion) is calculated from a difference between a maximum value and a minimum value of a waveform for every groove. With this arrangement, it is possible to calculate a position and a depth of an abrasion even on a piston 1 having several grooves left thereon during a short time operation.

Title: Shape measuring method of transparent body
Inventor: KOMINE HITOSHI
IPC: G01B11/24
Filed: 1993-06-18
Abstract: PURPOSE:To easily perform the high-accuracy shape detection of a transparent body such as glass, cellophane, plastic or the like. CONSTITUTION:Electromagnetic waves 1 having a wavelength which does not pass a transparent object 2 to be inspected are directed to the transparent object 2 to be inspected. The image of the transparent object 2 to be inspected is obtained by an image sensing part 3 having a light-receiving sensitivity to the electromagnetic waves 1. Thereby, a shape is measured. Since the transparent object 2 to be inspected cuts off the electromagnetic waves 1 completely, the image sensing part 3 can obtain the image whose contrast is high.

Inventor: ISHITANI AKIRA
IPC: G11B7/09
Filed: 1986-07-22
Abstract: PURPOSE:To decrease the off-setting quantity of a focus dislocation signal by equalizing an electric signal from respective elements when the areas of two adjoining elements are not equal out of respective elements divided into four for a four-divided light detecting device and the spot on the four-divided light detecting device comes to an approximately circle. CONSTITUTION:A projecting image by a light beam group on the incident surface of an objective lens 4 is a straight line, and passing through a converging lens 6 and a cylindrical lens 7, the projecting image on a four-divided light detecting device 18 is curved. The projecting image by a light beam group 11 of an orthogonal direction to a pit column 9 is also curved on the four-divided light detecting device 18. On the other hand, in a bus direction 14 of the cylindrical lens 7 and a direction 15 orthogonal to it, the light beam group of a 45 deg. direction is not curved and the light beam density in the spot on the four-divided light detecting device 18 comes to unequal. At the time of focusing, a spot pattern on the four-divided light detecting device 18 is round, the output from respective four-divided elements 18a-18d comes to the same, and the point in which the focus dislocating signal comes to zero is approximately central to respective focus surfaces of the front side and the rear side of the astigmatism. Thus, the off-setting of the focus dislocating signal is made smaller.

A difference detecting circuit 28 detects a difference signal according to subtract processing of Va-Vb, Vc-Vd, Va-Vd, and Vc-Vb to the output Va-Vd of the photo detecting elements 23A-23D. A determination circuit 29 determines a reflected image by computing the AND of all difference signals, and detects whether a difference signal exceeds a designated threshold level or not to determine the center of gravity moving state of the light emitting part.

Abstract: PURPOSE:To reproduce a picture without distortion by measuring the length of a spread book in the sub-scanning direction, obtaining a curved radius of a bound part and correcting a deformed picture. CONSTITUTION:In taking the X direction of the spread book 2 placed on an original placing plate 1 as the sub-scanning direction, when the size of the original of the book 2 opened is known, the curved radius (r) of the bound part of the book 2 is obtained by calculation by measuring the length 2(r+l) of the spread book 2 in the sub-scanning direction. Thus, the picture without distortion is reproduced from the picture of the bound part of the book placed on the original placing plate 1 by processing the picture information read at an original reader to correct the deformed picture.
